### 3/5 — When it works..

*2026-07-09*

When it works, by connecting properly, it’s fine. Having the ability to update OTA is terrific, but this app has huge problems staying or being able, to reconnect.

### 1/5 — Needs fixing please

*2026-06-27, version 1.7*

None of the buttons on the app work. Needs fixing please.

### 1/5 — Garbage app

*2026-06-26, version 1.7*

Pairing does stay static 
Have to pair for each use

### 1/5 — Buggy Mess

*2026-06-17*

I’ve been attempting to update the firmware for my Uniden R8W. After 30+ minutes of struggle it finally decided to do a DB update using the WiFi. Then I tried pairing the device back to the app after the update and now it won’t pair lol. What a mess. $800 device btw.

### 4/5 — Need single frequency low strength filter

*2026-06-06, version 1.7*

My 2026 CT5 constantly falses at Ka 35.100 one bar strength , probably from the entertainment system.  Lowering Ka sensitivity to 80% doesn’t help. Need a low strength Ka frequency filter without merely blocking off an entire Ka segment.

### 1/5 — Will Not Connect

*2026-05-15, version 1.7*

I have tried many times to get this to connect to my R8 with no success.  I use R8 Companion with no issues with connections.

### 1/5 — Hot steaming pile

*2026-04-30, version 1.7*

Just… no. Use anything BUT this app.

### 1/5 — Terrible

*2026-04-23*

Sometimes it connects, most times it doesn’t. Have to delete and reinstall often to connect to R8W detector. Would be a great app (I think) if connectivity issues were corrected. It’s disappointing.

### 3/5 — One problem

*2026-04-07*

Works brilliant with my new R8w. But there’s one huge problem: the app image does not rotate when my iPhone lies on its side, which is the holder I have for my iPhone on the dash.. So as far as I’m concerned, this is pretty useless.

### 1/5 — Useless. None of the function buttons work.

*2026-03-01, version 1.7*

What a waste of tine and money to develop such a pointless and useless app. None of the function buttons work either. 
Looks like I’ll be getting another Escort for the bike instead of another one of these Uni-don’t.
